is there a point at which going too cool w/ cause the tranny to not work right because it wont reach a good operating temp? For instance i wont take my racecar out on the track untill i have warmed the motor up to atleast 180*.

yep, i agree. i tow a fairly large camper with my truck and i watch the trans temp closely on my Edge and the most ive seen was 175-180 and that was stop and go in town traffic. cruising country roads or the highway it cools down a few degrees. that cooler does its job well.

i want to say no just because the oil in the tranny is different from motor oil. motor oil is primarily a lubricant while tranny oil is like hydraulic fluid. the pressure created by the oil pump in the tranny is used to activate clutch packs mainly, partially as a lubricant.

id be curious to hear about tranny temps from some of the guys who live in the snow. 60* is cold where i live so i have no experience with extreme cold

What do you want to know? It's not too cold here yet, but it was below freezing and didn't get above 40* today.

I know about the pressure and that stuff. thanks for reminding me. My concern is with the longevity because there have been so many posts with reguards to tranny trouble. I don't know about the wintertime temps, but I do know that quite a few of the auto tranny's I have had are a little slow to engage in gear. That could be contributed to pump pressure buildup. Caused by wear, dirt and so on.

how hot does your tranny get when its snowing?

I've only seen it to 152* during regular winter driving. It takes a looong time to warm up though, and I've noticed it doesn't shift into 4th until the tranny temp is over 80*.

Yeah, I used to get right out of my house onto the highway and my tranny would not shift into OD until a mile or more of going down the highway. Usually takes longer the cooler it is. we see temps below zero most mornings when i leave for work. Wonder if that is hard on the tranny? how would someone go about warming the tranny up before taking off?

ak_cowboy

I've got a tranny heater on mine It's plugged into a short multioutlet, so when I plug my block heater in, my tranny is warming up also.

did you have to put that in your pan or does that just "stick" to the bottom of your tranny?
